INS-11013-3 | Goldmann-X Type Tonometer

Goldmann Tonometer - X Type Best for Slit Lamp Zeiss Style

Tonometer is an important instrument to measure the intraocular pressure. Following the principle of Goldmann applanation tonometer, the applanation tonometer press flat a certain area (3.06mm diameter) of patient's cornea with different pressure through pressure-measuring probe inlaid with a prism. Under slit lamp microscope, and with the help of illumination of fluorescence and blue rays, two green semi-circles whose inner parts connect each other can be seen. Thus, numerical value of intraocuolar pressure (IOP) can be got from the reading turn drum. As the cornea area pressed flat by the tonometer is very small, change of IOP caused by outer force is also very small. The eye pressure we get is closer to the true value of IOP as compared with Schiötz tonometer, with the mean error no more than ±0.266Kpa. It is one of the commonly-used tonometer.
